Entry visas granted to foreigners act as a pledge of security which can't be breached
Dar al-Ifta` asserted that entry visas issued to foreigners are considered a pledge of safety. The same ruling applies for diplomatic relations which are strengthened through establishing embassies with other countries. The existence of these embassies is tantamount to a security covenant that does not require subsequent safety pacts.
In a reply to an extremist fatwa issued by some infidelizing websites, Dar al-Ifta` said that Islam promotes all virtues and that the Prophet [peace and blessings be upon him] was sent to perfect the best of morals. Moreover, the Holy Qur`an clarified that one of the characteristics of believers is that they fulfill their commitments and do not revoke covenants because it is one of the illicit traits.
In its fatwa, Dar al-Ifta explained that Muslims must not fight any country with whom they have a pledge of peace and whose treachery they fear except after they inform them of the pact’s revocation. Granting safety to others is a matter that must be respected by all Muslims.
It further said that Muslims must comply with a ruler’s pledge of safety and any aggression against tourists and their property and honor is impermissible.
